WILLIAM OWEN MILLER, OF G-ALENA, KANSAS.

ORE-WASHING MACHINE.

SPECIFICATION forming part of Letters Patent N0. 676,905, dated June 25,1901.

Application filed July 14, 1900. Serial No. 23.591- (No model.)

To a, whom it may concern:

Be it known that I, WILLIAM OWEN MIL- LEE, a citizen of the UnitedStates, residing at and whose post-office address is Galena, in thecounty of Cherokee and State of Kansas, have invented a new and usefulOre -W'ashing Machine, of which the following is a specification.

My invention is a machine to be used for the separation of valuableminerals from other material substances with which they are mechanicallymixed and for the separating of one valuable mineral from another wherethe minerals to be separated are of different density or specificgravity, carried in the sludge or slime or tailingsrunning from thecrushing-mills used in connection with the mining for valuable minerals.I attain these objects by the mechanism illustrated in the accompanyingdrawings.

' Figure 1 is a half top view of the machine. Fig. 2 is a verticalsection of the entire machine.

A circular concentrating-tank N is constructed, having two walls at suchdistance apart as will bear a proper proportion to the size of theore-washer desired to be constructed. In the center of the inner wall ofthe concentrating-tank a solid foundation I is laid, upon whichfoundation is permanently attached a metal cap from which projectsupward a pivot, this plate and the pivot therein forming the lowerbearing F, upon which the machine invented by me rests and revolves, andwhich machine consists of a castmetal feed-cup B, open at top and thebottom solid, with a socket in the outside of bottom and in the centerof it, such socket to fit over the pivot in the foundation-plate andconstituting the upper bearing G, the powershaft A entering a socket inthe bottom of feed-cup B, in which it is fastened by a set-screw H. Tothis power-shaft is firmly attached a rotating distributing-cone D abovethe separatingsurface, the' said cone being provided at its apex with acup 13, whichlies generally below the surface of the cone and isprovided with flanges overhanging said cone and a delivery devicecomprising a closed hollow ringO and spray-tubes depending from saidring nearly to the bottom of the cup, said cone being fastened to saidcup by bolts E and said feed-pipe O, surrounding the power-shaft A,being firmly suspended just above the mouth of the cup B. The materialto be worked is fed into feed-pipe 0 through an opening in its upperside from an elevated conveyer, and from feed-pipe O is fed into cup Bthrough the spray-tubes attached to feed-pipe O, the spray-tubes servingto further agitate the material in feed-cup B as it revolves. Therotating distributing-cone may be made of either metal or wood, and theslope and size of said cone may vary in proportion to size of feedcupand feed-pipe. To the outer rim of this cone is attached a band J,extending slightly above and below the rim of the cone, to which it isattached by bolts, upon which there are washers between the rim of thecone and the band, leaving an open space for the material fed upon thecone from the feed-cup to pass and fall into the concentrating-tank.Said cone is further supported and strengthened by a skeleton orframework beneath it. To the top of said cone and a short distance fromits place of attachment to feed-cup and at equal distances apart areattached four arms, rising a short distance perpendicularly from thesaid cone and then extending out horizontally from said feed-cup towithin a short distance of lines imaginarily extended perpendicularlyupward from the band J,

called broom-arms K, upon which are hinges or knuckles L, to which areattached broom extensions M, from which are hung 'into theconcentrating-tank canvas brooms.

The number of arms, extensions, and brooms can be varied with the sizeof the machine constructed.

The machine is operated by the power-shaft A coming down into feed-cupl3 and being screwed upon the threaded socket therein tributing-coneabove said surface, provided I at its apex With a cup which generallylies below the surface of the cone, and is provided with flangesoverhanging said cone, and a delivery device comprising a closed hollowring, and spray-tubes depending from said ring nearly to the bottom ofthe cup, substantially as described.

2. In an ore-washing machine the combination of a separating-surface, arotating distributing-cone above said surface, carrying sweep-arms andattachments, and provided at its apex with a cup which lies generallybelow the surface of the cone, and is provided with flanges overhangingsaid cone, and a delivery device comprising a closed hollow ring, andspray-tubes depending from said ring nearly to the bottom of the cup,substantially as described.
